iOS: The iPhone's default Photos app is okay, but if you want something a little prettier and smoother, PhotoSocial is a good alternative.

Photos is still our favorite photo management app, but only because Apple's restrictions make it hard for anything to work as well. That said, PhotoSocial is a pretty cool way to view and share the photos on your iPhone. It automatically splits your photos up into events (kind of like iPhoto does), and lets you manage them with gesture swipes. you can swipe to the left to remove it from the PhotoSocial gallery (but not from your phone), or swipe from the right to share it with other PhotoSocial users. You can share photos via SMS and email by tapping the "Share" button at the top, but we wish you had this option with the swipe gesture. PhotoSocial relies a bit too much on your friends having PhotoSocial too, which makes it much less enticing and useful if your friends don't have it (why not integrate with an existing service like Dropbox or Flickr instead?).
